To a/ZZ whom t may concern..d

Be it known that I, AUGUST LINDGREN, of Moline, county of Rock Island, and State of Illinois, have invented a new and useful Imf provement in Cultivators, of which the following is a specification.

This invention has reference to wheeled cultivators and consists in an improved sustaining and lifting mechanism forthe beams,

standards to the beams, and in certain other details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of the cultivator having my invention embodied therein, the beams being in their depressed operative position. Fig. 2 is a longitudinal central section with the beams elevated out of action. Fig. 3 is a zo sectional view on an enlarged scale of a device for securing the shovel standards to the beams. Fig. 4 is an elevation of the locking device for securing the hand levers to the standards when the beams are elevated.

Referring to the drawings, 1 represents an arched axle sustained by ground wheels.

2 represents two frame or draft bars seated and secured on the elevated portion of the axle and converging forwardly, their front 3o ends being connected to a draft tongue 3,

which is in turn connected to a cross bar 4, extending transversely of the machine and fixed securely to the frame bars. At their rear ends the frame bars give support to a 3 5 drivers seat 5. i

6 represents two beams each consisting of two short inner bars 7, extending parallel to each other and two long outer bars 8, connected at their forward ends to the inner bars 4o and diverging rearwardly. Each of the beams has fixed to its front end an upwardly curved bar 9, which bars are pivoted to the under sides of the frame bars on horizontal transverse axes. The beams are provided at suitable intervals with -shovel standards 9X, se-

cured thereto in a manner more fully de scribed hereinafter.

The foregoing parts may be of the usual and ordinary construction and except in so 5o far as hereinafter indicated they form no part of the present invention.

In applying my invention I firmly fix tothe Patent No. 541,975, dated July 2, 1895.

Serial No 541,327. (No model.)

upper sides of the frame bars at apoint over the axle two brackets or plates 10 and to the plates are bolted the lower ends of two uprights 1l, which are connected lat their upper ends by a horizontal rod 12 as plainly shown in Fig. 1. Upon this rod near its ends are loosely mountedtwo angular or elbow levers 13 which are pivoted at their rear ends to the 6o upper ends of two standards 14, extending downward and rearward to the beams where their lower ends are clamped in sockets formed in castings 15, seated between the two bars of the beams. The castings and standards are secured between the bars of the beams by horizontal bolts 16, the arrangement being such that the parts turn on the bolts with a pivotal movement. The front ends of the elbow levers are connected to the upper ends 7o of chains 17, which are connected to spiral springs 18, which latter are'in turn connected to two longitudinally extending hand levers 19, pivoted at their front ends on horizontal transverse axes, to the cross hars t before al- 75 luded to. These two levers are bent upward between their ends, the springs being connected to the upwardly bent portions the purpose of which will presently appear.

From the foregoing description it will be 8o seen that when the beams are in their depressed operative position, as shown in Fig. 1,` the elbowlevers will extend in nearly hori` zontal positions and the chains and springs will extend in a line with the forward portions of the handlevers, the springs in this manner sustaining the beams yieldingly, so that the latter will pass readily over any obstructions or unevenness of the ground in the usual manner. To elevate the beams toin- 9o operative positions the hand levers are depressed, as shown in Fig. 2, in which position the rear ends of the elbow levers will extend vertically, carrying the upper ends of the standards beyond their pivotal points, in which position the springs will tend to hold the parts. The hand levers are .engaged be neath locking lugs 20 on the standards in order to hold them in place.

. The shovel standards 9X before alluded to :oo are seated in vertical socketsformed in castings 21 which are bolted to the sides of the beam bars. Each casting is formed at. the side of the vertical socket with a horizontal longiudinally extending key way or socket into which a Wedge 22 extends, the arrangement `seing such that when the shovel standard is seated in its socket the wedge will engage the side of the same land hold it iXedly and firmly in place.

Having thus described my invention, I claiml. In a cultivator the combination with the frame of a beam jointed thereto, a standard pivoted at its lower end to the beam, a rocking lever sustained bythe frame and jointed to the upper end of the standard, a hand lever pivoted to the frame, suitable connections between the hand lever and rocking lever, and a locking device for securing the hand lever to the standard when the former is depressed.'

2. In a cultivator the combination of the wheeled frame, uprights risingl therefrom, beams jointed to the frame, standards pivoted at their lower ends to the beams, elbow levers pivotally sustained by the uprights and jointed at their rear ends to the upper ends ofthe standards, hand levers pivoted to the frame on horizontal transverse axes, springs connecting the hand levers with the forward ends of the elbowlevers and locking devices for securing the hand levers to the standards when the former are depressed.

3. In a cultivator the combination with the wheeled frame of beams pivoted thereto, standards pivoted at their lower ends to the beams, rocking levers sustained by the frame and pivoted to the upper ends of the standards, hand levers pivoted at their forward ends to the frame on horizontal transverse axes and bent upward between their ends, and springs connecting the rocking Vlevers with the upwardly bent portions of the hand levers whereby when the beams are lowered the chains and springs will extend in a line with the forward portions of the hand levers, thereby yieldingly sustaining the beams.

4. In a Wheeled cultivator the combination of the frame, beams jointed thereto, two uprights rising from the frame, a horizontal bar connecting the upper ends of the uprights, two elbow levers pivoted to said bar, standards jointed at their lower ends tothe beams and at their upper ends to the rear ends 'of the elbow levers, hand levers pivoted at their forward ends on horizontal transverse axes, spiral springs connected t0 said hand levers between their ends, chains, connecting the springs with the forward ends of the elbow levers and locking devices for securing the hand levers tothe standards when the former are depressed.

In testimony whereof I hereunto set my hand, this 20th day of February, 1895, in the presence ot' two attesting witnesses.
